2 PK Razor with 2 Refill Blade

This is my first time shaving so take my review with a grain of salt. While it worked pretty on other areas. I had a really hard time with my armpit hair. No matter how much I ran the razor through there was still stubs being left behind. It might just be due to uneven surface but it felt prickly even after 20 mins of shaving under just one arm. Additional the hair was a bit long so the razor got clogged many times and it was hard to remove the hair from between the blades.
